Насчёт кровососа я вот что скажу. Он человекообразный, он нуждается в еде, и у него есть полный набор органов, необходимых для функционирования. Да.
Откуда, действительно, берётся вот это, сутками бьющееся о стенки и которого пули не берут?

Я вообще сошлюсь на практику Уолтера Белла, который лично вскрывал дохлых слонов, чтобы выяснить, где именно в черепе моск. В итоге натренировался:"He shot elephants with a Mannlicher-Schoenauer 6.5x54mm carbine using the long 159 grain FMJ bullets and noted that it was probably the most beautiful rifle he ever had, but gave it up due to faulty ammunition.
He shot his first safari with a Lee Enfield in .303 British and the 215 grain army bullet. Thereafter he kept a ten shot Army& Navy Lee Enfield as a sort of back up and in the hope he might find ten elephants silly enough to stand around long enough for him to use the whole magazine.
He went to rifles chambered in .318 Westley Richards for a while, which is a .32 caliber cartridge firing a 250 grain bullet at about 2400 fps, but found the ammunition unreliable and again returned to the 7x57mm. He later wrote that the .318 Westley Richards was more of a reliable killer for certain shots, while the 7x57 was a "surgeons" rifle.
He also recorded that one of the reasons why he favored the 7x57 was that the ammunition was more reliable and he could not recall ever having a fault with it; whereas British sporting ammunition, apart from the .303 military ammo, gave him endless trouble with splitting cases.
He owned a .450/400 Jeffrey double rifle made by Thomas Bland & Sons, but did not use it after his first safari, as he considered the action not rugged enough and the Mauser repeating action to be just as quick as a double for aimed shooting.
He wrote about being able to drop an elephant with a light caliber rifle if he shot it in the same place that he would have shot it with a heavy rifle and realised this fully when he saw that elephants shot with a .303 died just as quickly when shot in the same place as a .450/400 double rifle with both triggers wired together, so they went off at the same time.
To judge ammunition expenditure and his own shooting, he calculated an average. He discovered that with the .275 (7x57mm) he fired an average of 1.5 shots per kill. This means that half the time he only needed one shot. That is a fair performance for such a large number of elephants killed with a rifle and cartridge that was intended for deer hunting".

А опытные сталкеры будут продолжать высаживать магазины в пустоту, чтобы не рушить атмосферу.
